A copper cable tester is a device for troubleshooting, inspecting, and certifying copper network cabling. Devices range from one-button tools for checking connectivity to complex tools for certifying network installations. Three types of testing include verification, to test whether a connection or cable is functioning correctly; qualification, to test a network's ability to support specific speeds and functionality; and certification, to verify whether a network installation meets industry standards. Cabling contractors, installers, and network technicians use copper cable testers to set up and maintain networks within a building or on a campus in corporate, academic, manufacturing, and other enterprise network environments.

Fluke Networks, a division of Fluke Corporation, manufactures tools and software for network deployment, performance management, and troubleshooting. The company, founded in 1992, is headquartered in Everett, WA.

Most Helpful Customer Reviews

[IMPORTANT NOTE]My original review below was written back in 2007, when the Sanyo eneloop first became availablethrough Amazon.com. Part of my initial estimation about eneloop's self-discharge rate turns out to be inaccurate. Please see my other Amazon spotlight review for updated information.http://www.amazon.com/review/R3TU586FEKG57A/

[Original Review follows]

According to Sanyo, the new eneloop LSD (low self-discharge) NiMH batteries can maintain 85% of its original charge after 1 year of storage. This claim is slightly misleading, because it is based on simulation test at 20 degree C. At higher temperature, the self-discharge rate is likely to be much higher.

I have tested five of those AA cells (details are given in my review for the eneloop 4-pack). The average energy loss is about 26% after less than 6 months of storage, based on manufacturer date codes. This self-discharge rate is about 3 times higher than what Sanyo claimed. However, it is still 6 times lower than that of ordinary NiMH batteries. Therefore I'm in the process of replacing most of my existing rechargeable cells to the Sanyo eneloop.

Thanks to lower self-discharge rate, you'll discover a lot more applications for eneloop cells in your house, such as in clocks and remote controls. Do NOT use those cell in smoke detectors, since their discharge voltage profile is very different from that of alkaline cells. Also, don't use them as emergency flash lights batteries in your car, because the higher temperature during summer time will probably nullify the advantage of LSD.

[Update on Jan 13, 2007]I have tested six new eneloop AAA cells, dated "2006-06'. The average residue charge is 589mAh, and the freshly charged capacity is 827mAh.Read more ›

I bought these batteries for use with my Canon S2 digital camera. I was having trouble with typical nimh batteries because I would charge a spare pair of batteries for use when the main pair died. But I was finding that the ones I charged a few weeks ago would be almost fully discharged by the time I would swap them. This was really annoying and pretty much defeated the purpose of having rechargeables... I had to use alkalines instead. But this new so called 'hybrid'/low discharge technology finally solves this problem. Of course it does not solve it completely because these batteries still discharge over time... just a lot slower, but at least now I know I have a pair of batteries that are at least 80 percent or so charged when I swap them. This technology was actually developed by an small independent company and licensed for use with all the major battery companies now. For instance, Sony is also utilizing it in their new batteries now. To me, this demonstrates how well it works.

So how does it hold up in real life? Pretty darn well, actually. I noticed that these particular batteries last really long in my Canon S2. I haven't had the problem of charged batteries being totally discharged by the time I swap them anymore. So if you're having similar problems with your older Nimh batteries, I would recommend giving these batteries a try. But don't feel limited to this brand, there are many other brands utilizing this technology and I've used other brands with the same great results.

Tip: If you live near a Fry's Electronics, they have a nice selection of battery choices that utilize this technology.

These 2100 mAh rechargeables are better than 2700 ones - Why - because the regular but higher capacity ones lose charge so quickly, within 10 days they have less charge left in them than the "eneloop" type.

I had some doubts how they would perform in the real world - in particular, their peak current capability (which will determine how well they actually work in a digital camera). Turns out - they do better than the regular ones. While my 1600 mAh panasonics gave approx 40 - 50 shots consistently, the same digital camera now gives me approx 100 shots with these eneloops. Suddenly my mom's camera which "ate up battery very quickly" - has become a "great camera" from the battery change. If she's happy, so am I. Incidentally - the amazon price is also very good - you can also try getting the ones with a charger - this eneloop charger charges batteries INDIVIDUALLY. This is critical - no matter which charger you buy - get ones that charge batteries individually and not in pairs. Also remember to always mark your batteries, so you don't mix up charged and discharged batteries when charging them. I've found this to be a common problem with many users.

I have a 5 MP digital camera that only uses 2 AA batteries and was getting very finicky about the Energizer and Rayovac rechargeable NiMH batteries I supplied it with. I like to charge up my batteries and keep a spare set in my camera case for backup. However, I was continuously putting in the fresh batteries and the camera wouldn't even power on. It would say "Change batteries". It was baffling b/c batteries that were totally charged were not working any more. The only thing I could figure is that because NiMH AA batteries are only 1.2 Volts instead of the standard 1.5, anything less than a full charge would not supply the camera with a high enough voltage to power on. Then I started reading about batteries and discovered that these things lose charge surprisingly fast when sitting in storage. I bought four Eneloop batteries and tried them. I have been amazed at the performance with my digital camera. With the previous brands of NiMH, I could maybe get 120 pictures from the camera. Now I can go almost double that time. Don't ask me why. Part of that reason is probably due to the fact that I don't use my camera for significant amounts of time between shoots. So the eneloops hold that charge MUCH better. Anyway, foot the extra cost of these batteries and order plenty of extras. You'll be glad you did when using high-drain devices!
